Specification of Letters Patent.

" Patented Maya, 1915.

Application filed May 26, 1914. Serial No. 841,161.

To all whom it may concern:

Be it known that I, Gasrnn L. WADDELL, a citizen of the United States, residing at Grapeland, in the county of Houston and State of Texas, have invented new and useful Improvements in Extensible N eck- Yokes, of which the following is a specification.

The invention provides a neck yoke which may be lengthened or shortened to meet varying conditions and has for its object to provide novel means for securing the adjustable sections in the required position, such means utilizing the strain upon the neck yoke straps as means to prevent slipping, even though the main fastening means should become loose.

The invention consists of the novel features, details of construction and combination of parts, which hereinafter will be more particularly set forth, illustrated and claimed.

In the drawings hereto attached: Figure 1 is a detail view "of a neck yoke embodying the invention. Fig. 2 is a detail section. Fig. 3 is a detail view showing more clearly the fastening means whereby the movable sections are held in the adjusted position.

Corresponding and like parts are referred to in the following description, and indicated in all the views of the drawings, by the same reference characters.

The neck yoke comprises a main section 1 and end sections 2 which are adjustable and have telescopic connection with the main sec tion to admit of the neck yoke being lengthened orshortened as required. The sections 1 and 2 may be of any construction and it is preferred to form the same of lengths of tubing, the end sections 2 being of such relative size as to slide within the section 1. Rings 3 are attached to the outer ends of the sections 2 and are adapted to have the straps leading from the collar attached thereto. The main section 1 may be attached to the pole or tongue in any manner to admit of the neck yoke having the usual movements. A longitudinal slot 4 is formed in a side of the section 1 and a plurality of notches 5 communicate with the rear edge of the slot 4 being formed in the edge portion of the section bordering upon the rear side of the slot 1. Screws 6 are threaded into the sides of the sections 2 near their inner ends and are adapted to operate in the slot 4: and to thereby retaining.

enter selected notches 5, the end sections 2 in the The heads of the screws overlap portions of the section 1 bordering upon the notches 5 so that when the screws 6 are tightened they are retained in the notches 5 and prevent possible slipping of the sections. Each of the rings 3 has a straight portion which passes through the section 2. The rings are positioned in such a manner that when under strain incident to a pull upon the neck yoke they tend to turn the sections 2 so as to press or hold the screws 6 in the notches 5 thereby preventing possible slipping of the sections, even though the screws 6 should become loose.

The neck yoke may be lengthened or shortened by loosening the screws 6 and turning the screws from the notches 5 after which the sections 2 may be drawn outward or pushed inward and when the sections 2 have reached the desired quired length of the neck yoke the sections 2 are turned backward to bring the screws 6 into registering notches 5 after which such adjusted position. 6 are adapted to screws are tightened to clamp the section 1 so as to hold the sections 2 in the adjusted position.

From the foregoing description, taken in connection with the. accompanying drawings, the advantages of the construction and of the method of operation will be readily apparent to those skilled in the art to which the'invention appertains, and While I have described the principle of operation of the invention, together with the device which I now consider to be the best embodiment thereof, I desire to have it understood that the device shown is merely illustrative, and that such changes may be madewhen desired as are within the scope of the invention as claimed.

Having thus described the invention, what is claimed as new is A neck yoke comprising a main section having a longitudinal slot and notches along one edge of the slot in communication therewith, and sections slidable within the main sections 2 to disengage the,

position according to the re- (1 section, screws threaded into the sides of the the receiving notches even though such end sections and arranged to move from the screws should be loose. 10 longitudinal slot of the main section and en- In testimony whereof I aflix my signature ter selected notches thereof to hold the end in presence of tWo Witnesses.
